A turbines blade accelerates from 1.74 x 10^4 rad/s to 4.75 rad/s. During the acceleration the blades make 4.4 x 10^3 revolutions.
a) what is the angular acceleration?
b) how long will it take the fan blades to reach an angular velocty of 7.64 x 10^4?
Homework Answers
Answer #1
I here answer acroding to the given problem. But i fell that angular velocity given (4.75 rad/s) may be other value as written it accelerated .
If you have another value then inform me i can repost the solution again
Not the answer you're looking for?
